You are lacking facts - Sarah is going to meet world leaders, she in fact is going to Israel this spring, she also has been invited to England to meet leaders of the Torie party and see Margaret Thatcher
As far as raising money - money collected by her PAC cannot be raised for a Presidential run, once you run for President or do an exploratory committee then you can raise funds
Last Summer Politico did a study of her PAC organization and discovered that it looks like it’s being ready to switch over to a Presidential organization easily, she hired an giant donor list group and foreign advisers
And the last but most important thing is that there is none out there like her, Mitt, Thune, Pawlenty, Daniels, Newt are not the most charismatic or Tea Party liked candidates, if she is in the race no matter how “overexposed” you think, people are not going to turn away from her without listening to what she has to say, which will be going after the Establisment as well as the Dems, which the others won’t do.
That is so cool. I so wanted that to happen a few years ago during the campaign. There is no doubt that Palin is an amazing person. A real heroine to me.
